Servicing outer sliding constant velocity joint (88 mm or 98 mm dia.) Special tools and workshop equipment required t  Circlip pliers (commercially available) t  Copper or brass drift t  For correct sealant refer to → Electronic parts catalogue

Removing outer sliding constant velocity joint (88 mm or 98 mm dia.) –  Clamp drive shaft in vice using protective jaw covers. –  Open hose clips. –  Push back boot. –  Use drift -A- to force sliding constant velocity joint off drive shaft. Drift -A- must be positioned exactly on spider of sliding constant velocity joint.

–  Detach joint and boot. –  Detach circlip -1-.

Installing outer sliding constant velocity joint (88 mm or 98 mm dia.) –  Push joint boot onto drive shaft. l  Boot and drive shaft must be free from grease. –  Position boot between -arrows-. –  Pack 60 % of drive shaft grease evenly into inside of joint body.

–  Grease splines -A- on drive shaft lightly with grease used in joint before fitting joint body onto drive shaft. –  Fit circlip in groove on shaft.

–  Slide on constant velocity joint as far as circlip. –  Align circlip so that opening faces upwards -arrows-.

–  Screw old bolt into CV joint as shown. –  Use plastic hammer to drive joint onto drive shaft until circlip engages. –  Fit boot on metal cap. –  Vent air from boot. –  Tighten hose clips on outer joint. Tightening hose clip on outer joint Applies to small and large hose clips. Use the following tools depending on type of hose clip: Special tools and workshop equipment required

t  Pliers -3340-

t  Clamp tensioner -V.A.G 1682-

t  Torque wrench -V.A.G 1331-

Use clamp tensioner -V.A.G 1682- to fit and tighten stainless steel clips, as shown in illustration. –  Ensure jaws of tool make contact with lugs -arrows B- on hose clip. –  Tighten hose clip by turning spindle with torque wrench (take care to keep clamp tensioner straight). t  Due to the hard material of the CV joint boot (as opposed to rubber), a stainless steel hose clip is required; this can only be tightened using clamp tensioner -V.A.G 1682-. t  Tightening torque: 20 Nm. t  Use torque wrench with 5…50 Nm adjustment range (e.g. -V.A.G 1331-). t  Make sure thread of spindle on tool -A- turns freely. Lubricate with MoS2 grease if necessary. t  If the thread is stiff (e.g. due to dirt), the required clamping force will not be attained at the hose clip when the specified tightening torque is applied.

Use pliers -3340- to fit and tighten clips with retaining lugs, as shown in illustration. –  Engage hose clip by hand at first lug. –  Use pliers -3340- to fasten hose clip.
